How did you solve your issue?

[MAXI279]

The problem is solved, it was related with this error "cURL error 60: SSL certificate problem: unable to get local issuer certificate (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)"

So i add a cacert.pem downloaded from https://curl.haxx.se/ca/cacert.pem into php.ini

; A default value for the CURLOPT_CAINFO option. This is required to be an
; absolute path.
curl.cainfo = "absolute route in server"

and problem solved. thanks

Hello Nyholm I also got following error - "Could not get access token: The user may have revoked the authorization response from LinkedIn.com was empty. "

I read a lot. But not find answer. Could you give me sample code, how to get access token from 'code' (after user allow access) and so I can store in db.. For reference I have attached my code snippet here. Could you please help me in this My symfony2 application code is below-- `/**

• @Route("/linkedin/callback", name="social_linkedin_callback", options={"expose"=true})
• @Method("GET")
• @param Request $request

• @return array */ public function linkedinCallbackAction(Request $request) { $session = new Session(); $params = $request->query->getIterator()->getArrayCopy(); $responseData = [];

  //get session state
  $oauthState = $session->get('oauth_state');
  
  //check does 'state' param is same which we set in session
  if (isset($params['state']) && $oauthState == $params['state']) {
  
      $linkedIn = new LinkedIn($this->container->getParameter('linkedin_credential')['consumer_key'],
       $this->container->getParameter('linkedin_credential')['consumer_secret']);
  
      //here error comes when calling getAccessToken method
      $accessToken = $linkedIn->getAccessToken();
  
      //access token is not get from this method
      //Todo: Save access token in db
  
  } else {
      $responseData['success'] = FALSE;
      $responseData['message'] = 'Invalid request, State is not matched. ';
      $session->set('socialResponse', $responseData);
  }
  
  return $this->redirect($this->generateUrl('social_setting', array(), true), 301);

  }`
